Iodine sublimation

Caption: Iodine sublimation in a fume cupboard. At room temperature iodine is a purple/black solid. Gentle heating over a bunsen burner results in the formation of a purple gas. This solid-gas transition with no liquid phase is known as sublimation. Fume cupboards are used in laboratories to extract potentially harmful gases and smoke.
